Lennon (1863) stated that it was not common, but that it had occurred at Tinwald Downs (VC72). Sir Arthur Duncan (1909-84) during his lifetime had found it at Closeburn and Tynron (VC72).

During 1974-92 just three of the seven Rothamsted stations recorded it and that was only twelve times. The sites were Gatehouse of Fleet and Mabie Forest (VC73) and Caerlaverock (VC72). During regular trapping on the Hensol Estate/Laurieston in the early 1980s it was recorded just six times.

During a three day visit in August, 1987, Bernard Skinner found it at Sandhead, the first record for Wigtownshire. It has since been recorded twice more, being found at Torrs Warren in 1997 and trapped on Forest Moor in 2006.

From 1992-2001 forty records came from Kirkton (VC72), the next most popular sites between 1992-2010 were Castle Loch at Lochmaben (VC72), Auchencairn and Mersehead RSPB (VC73). A small scattering of further records, same period, were mostly from Kirkcudbrightshire.
